<P><STRONG>Function</STRONG>
<P>Renders an Object into an image.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
Field DXRender(Object o, Camera c, char *format)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>Renders all objects in
<TT><STRONG>
o
</STRONG></TT>
using the Camera defined by
<TT><STRONG>c</STRONG></TT>.  It returns a
new image Field containing the result.  This routine performs the
transformation, shading, and the tiling steps.
<P>If
<TT><STRONG>
format
</STRONG></TT>
is
specified as
<TT><STRONG>NULL</STRONG></TT>,
a generic floating-point image is created;
this is the
most flexible format with
respect to processing by other modules.
Alternatively,  <TT><STRONG>format</STRONG></TT>
may be specified as a character string
identifying a hardware-specific format that may be used only for
display on a particular hardware device.  <TT><STRONG>format</STRONG></TT>
currently must begin with &quot;X&quot; for
an image that will be displayed on an X server image window, or
&quot;FB&quot; for an image that will be displayed on an IBM 7246 Video
Controller.  Any
other string will generate a generic floating-point image.
<P>A renderable Field must have at least a &quot;positions&quot; and a
&quot;colors&quot; component.  For anything other than scattered points,
a &quot;connections&quot; component is needed. Many other components
and attributes affect the output of <TT><STRONG>DXRender</STRONG></TT>.  For
additional details on the rendering process,
see <A HREF="progu075.htm#HDRRENDCHP">Chapter 16. "Rendering"</A>.
<P><STRONG>Return Value</STRONG>
<P>Returns the image, or
returns
<TT><STRONG>
NULL
</STRONG></TT>
and sets the error code to indicate an error.
